Sheet Metal Forming
Descripción del editor: "heet forming fundamentals are thoroughly addressed in this comprehensive reference for the practical and efficient use of sheet forming technologies. The principle variables of sheet forming-including the interactions between variables-are clearly explained, as a basic foundation for the most effective use of computer aided modeling in process and die design.Topics include stress analysis, formability criteria, tooling, and materials for sheet forming. The book also covers the latest developments in sheet metal forming technology, including servo-drive presses and their applications, and advanced cushion systems in mechanical and hydraulic presses."

Computer-Supported Collaborative Learning at the Workplace
This book is an edited volume of case studies exploring the uptake and use of computer supported collaborative learning in work settings. This book fills a significant gap in the literature. A number of existing works provide empirical research on collaborative work practices (Lave & Wenger, 1987; Davenport, 2005), the sharing of information at work (Brown & Duguid, 2000), and the development of communities of practice in workplace settings (Wenger, 1998). Others examine the munificent variation of information and communication technology use in the work place, including studies of informal social networks, formal information distribution and other socio-technical combinations found in work ...
Engineering Education 4.0
This book presents a collection of results from the interdisciplinary research project “ELLI” published by researchers at RWTH Aachen University, the TU Dortmund and Ruhr-Universität Bochum between 2011 and 2016. All contributions showcase essential research results, concepts and innovative teaching methods to improve engineering education. Further, they focus on a variety of areas, including virtual and remote teaching and learning environments, student mobility, support throughout the student lifecycle, and the cultivation of interdisciplinary skills.
Smart Technologies for Improved Performance of Manufacturing Systems and Services
This book discusses smart technologies and their influence in the field of manufacturing and industrial systems engineering, in the context of performability enhancement, and explores the development of the workforce for the execution of such smart and advanced technologies. Smart Technologies for Improved Performance of Manufacturing Systems and Services discusses the integration of smart technology into the production process and supply chain to enhance the overall performance of manufacturing industries.

Machine Learning Algorithm for Fatigue Fields in Additive Manufacturing
Fatigue failure of structures used in transportation, industry, medical equipment, and electronic components needs to build a link between cutting-edge experimental characterization and probabilistically grounded numerical and artificially intelligent tools. The physics involved in this process chain is computationally prohibitive to comprehend using traditional computation methods. Using machine learning and Bayesian statistics, a defect-correlated estimate of fatigue strength was developed. Fatigue, which is a random variable, is studied in a Bayesian-based machine learning algorithm. The stress-life model was used based on the compatibility condition of life and load distributions. The defect-correlated assessment of fatigue strength was established using the proposed machine learning and Bayesian statistics algorithms. It enabled the mapping of structural and process-induced fatigue characteristics into a geometry-independent load density chart across a wide range of fatigue regimes.
Numerische Simulation dreidimensionaler Umformvorgänge mit Einbezug des Temperaturverhaltens
In diesem Band wird die Entwicklung eines auf der Finite-Elemente-Methode aufbauenden Simulationsverfahrens für die Kalt-, Halbwarm- und Warmmassivumformung beschrieben. Das Verfahren liefert detaillierte Informationen über die plastische Werkstückdeformation sowie Wärmeentstehung und Temperaturausgleich bei Massivumformvorgängen. Die Methode basiert auf dem Markovschen Extremalprinzip und ist auf isotrope, inkompressible Werkstoffe beschränkt. Das starrplastische Fließverhalten wurde mit Hilfe des Stoffgesetzes nach Lévy-Mises erfaßt (bei technischen Vorgängen der Massivumformung können die elastischen und temperaturbedingten Formänderungsanteile gegenüber den plastischen verna...
Digital Didactical Designs
As web-enabled mobile technologies become increasingly integrated into formal learning environments, the fields of education and ICT (information and communication technology) are merging to create a new kind of classroom: CrossActionSpaces. Grounding its exploration of these co-located communication spaces in global empirical research, Digital Didactical Designs facilitates the development of teachers into collaborative designers and evaluators of technology-driven teaching and learning experiences—learning through reflective making. The Digital Didactical Design model promotes deep learning expeditions with a framework that encourages teachers and researchers to study, explore, and analyze the applied designs-in-practice. The book presents critical views of contemporary education, theories of socio-technical systems and behavior patterns, and concludes with a look into the conceptual and practical prototypes that might emerge in schools and universities in the near future.
Targeted Use of Forming-Induced Residual Stresses in Metal Components
Residual stresses are considered critical to quality in conventional manufacturing strategies. This is where the DFG’s Priority Programme 2013 comes in, looking instead at the opportunities and possibilities for improving the properties of components by targeted use of residual stresses. In the years 2017 to 2023, research teams from all over Germany were able to prove the stability, controllability and usefulness of residual stresses in flat and solid forming manufacturing processes of metallic components. In addition, the cross-project working groups achieved many insights into the fundamental understanding, simulation and, in particular, industry-oriented measurement of residual stresses. The extensive results of these six years of research activities are presented in this final report.
